多向地震作用下地下结构响应分析
|
摘要
目前地下结构的抗震分析主要是考虑水平横向地震波的作用,一般忽略水平纵向和竖向地震的影响。论文针对某一长度和宽度相差较大的地下建筑结构,建立其三维有限元计算模型,计算分析其在水平横向、水平纵向以及竖向等多向地震荷载作用下的地震响应规律。计算分析表明,对于长度和宽度相差较大的地下建筑结构,仅考虑水平横向地震作用是不够的。其结果可为地下结构的抗震分析提供参考。
Currently,only lateral-horizontal seismic load is considered in seismic response analysis of underground structure,and the seismic loads in longitudinal-horizontal direction and vertical direction are usually neglected.In this paper,an underground structure,whose length was much larger than the width,was considered.The three-dimensional model for finite element analysis was established and its dynamic responses under lateral,longitudinal and vertical seismic loads were analyzed respectively.The results show that it is not enough to consider lateral horizontal seismic load only for this type of underground structure.The results provide a reference for anti-seismic design of underground structures.
